The Blackbirds nesting in my Honeysuckle reported last month, completed the nest. Hen bird was seen sitting on the nest, and gave cry when my wife went up to the propagator. However one of next door's cats found a way up to the nest by walking along the top of the oil tank and jumping up onto the Honeysuckle. They have been frightened off and now seem be to nesting in the big Conifer in the garden behind ours. Although we saw a black cat about fifteen feet up the Conifer yesterday. The hen bird really scolds us when she sees us as if it is our fault the cats are invading their nest spaces. I only wish I could do something as I have five cats one side and two the other . Having lost a Goldfinches nest in the Laburnham tree outside my bedroom window a couple of years ago, I am off moggies!!
